Hey guys I have a 99 gmc sierra z71 ecsb. I recently had mb quart premiums and they blew after 2 years. I really loved my 6.5" premiums so I decided to step up in the MB quart line to the qsc's. these are not the same as the QSD's which is MB quarts best components But they were just recently released they are still supposed to be top of the line speakers, better then the premiums i previously had. So without even hearing the speakers before I bought them, which I was very skeptical about because every other set of components ive bought Ive listened to before purchasing I decided to go ahead and give these a shot. They retail for 850 bucks but I got them Off ebay brand new for 325$ shipped!!! I had them put in last weekend hooked up to my j/l 500/5 amp along with 1 Jl audio 10w3v3 in a sealed box upfiring under the rear seat and this thing rocks out hard... These speakers were badder then I thought they were going to be. I prefer very bright highs and these speaker definetly have plenty of that. Even though the tweeters are so bright they dont scream and get distorted at all they stay clean throughout the whole range of volume on my alpine head unit. This is the best sounding system I have ever had.
